One thing that seems to be forgotten in this discussion is that it is entirely possible that a commands has no 'inherant' path. Take for example a resident command (written in C and made residentable) that is on the resident list. When it is run, there is no path that it came from... The only way to work in the presence of the various shells (which may have hidden paths such as WShell) is to utilize the (admiditly ugly) method of creating an overlay program which WILL retain an open handle on the original file. This has the one problem of not being able to locate the directory as all you have is a file handle. Converting from a file handle to a lock is not a legal operation (currently)... However you do have the ability to store information as part of the file itself. Have you considered environment variables??? :-) :-) :-) -- |0|\ John A.
